This article presents a comprehensive hydrometeorological dataset collected over the past two decades throughout the Cordillera Blanca, Peru. The data-recording sites, located in the upper portion of the Rio Santa valley, also known as the Callejon de Huaylas, span an elevation range of 3738–4750 m a.s.l. As many historical hydrological stations measuring daily discharge across the region became defunct after their installation in the 1950s, there was a need for new stations to be installed and an opportunity to increase the temporal resolution of the streamflow observations. Through inter-institutional collaboration, the hydrometeorological network described in this paper was deployed with the goal of evaluating how progressive glacier mass loss was impacting stream hydrology, and understanding better the local manifestation of climate change over diurnal to seasonal and interannual time scales. The four automatic weather stations supply detailed meteorological observations and are situated in a variety of mountain landscapes, with one on a high-mountain pass, another next to a glacial lake, and two in glacially carved valleys. Four additional temperature and relative humidity loggers complement the weather stations within the Llanganuco valley by providing these data across an elevation gradient. The six streamflow gauges are located in tributaries to the Rio Santa and collect high-temporal-resolution runoff data. The datasets presented here are available freely from https://doi.org/10.4211/hs.35a670e6c5824ff89b3b74fe45ca90e0 (Mateo et al., 2021). Combined, the hydrological and meteorological data collected throughout the Cordillera Blanca enable detailed research of atmospheric and hydrological processes in tropical high-mountain terrain.

在热带科迪勒拉布兰卡收集的高分辨率水文气象数据，秘鲁（2004-2020）

本文介绍了过去二十年来在秘鲁布兰卡山脉收集的综合水文气象数据集。数据记录站点位于 Rio Santa 山谷的上部，也被称为 Callejon de Huaylas，海拔范围为 3738-4750 m asl，因为许多测量该地区每日流量的历史水文站在其建成后不复存在。在 1950 年代安装时，需要安装新的台站，并有机会提高流量观测的时间分辨率。通过机构间合作，部署了本文中描述的水文气象网络，目的是评估冰川质量损失如何影响河流水文，并更好地了解气候变化在昼夜到季节和年际时间尺度上的当地表现。四个自动气象站提供详细的气象观测，位于各种山地景观中，一个位于高山通道，另一个位于冰川湖旁边，两个位于冰川雕刻的山谷中。四个额外的温度和相对湿度记录仪通过在海拔梯度上提供这些数据来补充 Llanganuco 山谷内的气象站。六个流量测量仪位于 Rio Santa 的支流中，用于收集高时间分辨率的径流数据。此处提供的数据集可从 https://doi.org/10.4211/hs.35a670e6c5824ff89b3b74fe45ca90e0（Mateo 等人，2021 年）免费获得。结合，
